using System.Data.SqlClient;
     //SqlDataAdapter使用
       SqlConnection con = new SqlConnection();
            con.ConnectionString = "Server=.;uid=sa;pwd=sa;database=db_PMS";
            con.Open();
            DataTable dt = new DataTable("Resouce");
            string SqlIns = "insert into tb_user values('" + textBox1.Text + " ','" + textBox2.Text + "')";
            SqlCommand command = new SqlCommand(SqlIns, con);
            SqlDataAdapter adapter = new SqlDataAdapter();
            adapter.SelectCommand = command;
            adapter.Fill(dt);
            dt.Clear();
            SqlDataAdapter AdapterSelect = new SqlDataAdapter("select * from tb_User", con);
            AdapterSelect.Fill(dt);
            dataGridView1.DataSource = dt.DefaultView;
    我运行的时候，提示adapter.Fill(dt);出现异常 , DataTable dt = new DataTable("Resouce");这条语句什么意思不明白。Resouce 是什么意思？


       //添加

              using System.Data.SqlClient;

try
            {
                SqlConnection conn = new SqlConnection();
                conn.ConnectionString = "Server=.;uid=sa;pwd=sa;database=db_PMS";
                conn.Open();
                string SqlIns = "insert into tb_department values('" + textBox1.Text + "','" + textBox2.Text + "')";
                SqlCommand command = new SqlCommand();
                command.CommandText = SqlIns;
                command.Connection = conn;
                command.ExecuteNonQuery();
                MessageBox.Show("数据库添加成功!");
                SqlDataAdapter AdapterSelect = new SqlDataAdapter("select * from tb_department", conn);
                DataTable dt = new DataTable();
                AdapterSelect.Fill(dt);
                dataGridView1.DataSource = dt.DefaultView;

            }
            catch (Exception ee)
            {
                MessageBox.Show(ee.Message.ToString());
            }

        运行没有反应
